M3a Emergency doors can't be opened. Serious signalization issues. a) While i was on the station with my train an Ai train almost hit me. It stopped approximately 5 feet from the back of my train. b) The signal is yellow but after that signal there is an Ai train in front of me. So that damn signal should be RED not yellow.
For the AI train issue pay attention to the L (45mph), M (30mph) and R (15mph) that appear in the HUD bottom right. It's in the tutorial. Follow the line speed unless you see one of those letters come up and if they do follow the speeds for the corresponding letter above and you will avoid the AI
Yellow is continue, but look out and stop short of any obstructions. Make sure your in cab signalling is switched on. Aside, as I have not bought the route yet - does the AI continue past a steady yellow at linespeed rather than a slow speed?
I believe AI always ignored signal aspects and ATC and just continue at track speed.on every route. So I suppose it's the case here as well.
